This gasket tape whitepaper discusses silicone product options that will last and perform for the entire anticipated life of the electrical equipment including those installed in outdoor conditions in the harshest environments.

What is Strip-N-Stick® Gasket Tape?

Strip-N-Stick® is the branded silicone sponge and silicone foam product line of high temperature silicone gasket tape manufactured by Saint-Gobain. Products include SNS-100S, SNS-200A, SNS-300AR, SNS-512.

Saint-Gobain Strip-N-Stick® is not currently listed for UL 50/E however it is widely used for NEMA enclosures and high temp masking applications. The closed cell silicone sponge is tougher and has a wider temperature range than silicone foam. SNS-100S is provided with a silicone adhesive allowing for a wider operating temperature (-100° to 500°F). The silicone adhesive on SNS-100S has a short shelf life – users are advised to store this particular product in a temperature controlled environment and use within 90 days.

Gasket Tape with DP-1001 Silicone Adhesive for Extreme Conditions

Stockwell Elastomerics offers 3 gasket tapes with DP-1001 silicone adhesive backing in slit-to-width rolls. With proper deflection, they can be used to seal out rain, withstand outdoor conditions and temperature extremes. These gasket tape products have been specified for long-term sealing of outdoor enclosures, industrial ovens and dryers, ventilating and airflow applications subject to temperature extremes.

DP-1001 silicone adhesive contains an amber colored polyimide film support layer that provides dimension stability when removing the release liner and installing the gasket strips. The polyimide film layer improves the shelf life of the silicone adhesive backing by preventing migration of the adhesive into the silicone sponge or foam. The polyimide film also withstands a temperature range of -100°F to +500°F, thereby not limiting the performance of the silicone gasket in extreme temperature conditions. DP-1001 silicone adhesive is a total of .005” thick and has an easy peel release liner to aid installation.

The 3 gasket tapes with DP-1001 silicone adhesive are:

R10470-M closed cell silicone sponge, provided by Saint-Gobain is UV resistant, will provide long service life in rugged conditions and meets ASTM D6576, Type 2, Grades B and C.

BF-1000 low density, open cell silicone foam is provided by Rogers Corporation, passes the UL 94V-0 flame rating and is frequently used for air diverting and dust sealing.

Need Help with a Custom (Made-to-Order) Foam, Sponge and Adhesive Combination?

Stockwell Elastomerics can provide guidance on selecting the proper gasket tape material and adhesive backing for specific customer applications. A film support adhesive backing to prevent stretching during assembly may be recommended, or a transfer film adhesive to allow for making corners and radii as assembly technicians install the gasket tape. Stockwell Elastomerics regularly supplies silicone foams with low surface energy acrylic adhesives for powder coated surfaces.

DP-1001 polyimide film supported silicone adhesive from Stockwell Elastomerics allows silicone foam and silicone sponge gasket tape with broad temperature range and longer shelf life to be supplied. The polyimide film support serves as a barrier to prevent the user side of the silicone adhesive from cross- linking prematurely – and allows for an extended shelf life compared to the SNS-100S.

Frequently Asked Questions

Q: What is the minimum order requirement for custom gasket tape? A: It is most efficient and causes less waste to use the full width yield from a 34” wide adhesive backed master roll – which is laminated per order. Therefore, if the best yield length is 15 linear feet, and the selected gasket tape width is 1.00”, the yield would be 34 slit rolls x 15 linear feet / roll = 510 linear ft.

Q: Is it possible to evaluate a sample of a custom order foam, sponge and adhesive combination before we order? A: Yes. Stockwell Elastomerics’ sample department can provide a 6″ x 6″ sample swatch of the chosen thickness and type of gasket material with the requested adhesive to confirm compatibility with the surface to which the gasket tape will be applied.
